Introduction: Making 3"x5.5" Mono and Bi Planes! That Fly!!!(over 15 Ft)

You can make mono and bi plane gliding models with this instructable!
Next up, the paper jet-engine!, also the bi-prop pontune plane(looks mega-cool
Should I post them?

Step 1: Supplies

General supplies for this project.
I am going to instruct you in the creation of mono and bi planes together.

Step 2: Make the Fusalage for the Planes

First, observe the photo, the top card displays the monoplane, the bottom the biplane.
Cut on the solid lines, and the dotted lines. Discard noted pieces.

Step 3: Fabricate the Wings

On the monoplane, fold the wing pieces so they are at a 90 deg angle to their previous location.
There should be a triangular point, which should be folded down.
Open the wings, and flip the plane so you cant see the triangles.
Fold the front of the wings back a little, so it looks like th image. Fold the little piece of the triangles down now. Tape.
For the biplane, fold a fresh card hotdog style (longways) and then fold it hamburger style (shortways).
Your fresh card should now be divided into four quadrants with creases.
Cut the card on the line, and discard the smaller piece.
Fold the tip in the center down and crease.

Step 4: Completing the Monoplane

View the accessory card, and cut out the pieces.
tape the tail on, then the cockpit. Next, tape the wings together at the front. and add paperclips. The next series of images will show you the construction of the prop.

Step 5: Building the Prop

use the bearing and prop pieces from the two planes, as well as two paperclips to make the props.
Just follow the directions on the images.

Step 6: Finish the Biplane

Get the fuselage and wings, and a fresh card.
Fold the card in half, and draw the accessories on. cut them out, and proceed to attach them. add paperclips for weight, and add the prop. Congrats! Nice plane!

Step 7: Making Them Fly.

You need to bend the front tips of the tail wings down at a 45 deg angle, this makes the rear of the plane wan to fly down, and if you throw in the lift from the front wings, the plane will stay airborne.
This would be equivalent to turning the ailerons (control surfaces on the rear wings) up, to adjust the angle of attack on the front wings. Without this adjustment to the plane, it would make a tight loop downwards, and hit the ground. Fiddle around with the tail wings and tail until it flies the way you want it to. If the plane isn't going fast enough to fly, increase the angle of attack on the prop, to allow more air past with less rotations. You want to increase the length of v0 on the diagram (allows more air past) eg: twist it more

    ever thought about adding a more solid body like a small dowel or the like and putting a rubberband to a prop to give it power flight? would love to see if its possible

    Is the bearing just rolled up cardstock that has been taped?

    I might recommend scale templates, to ease building these.

    This thing looks awesome, but does it fly or is it just a display piece is the question.. that would be really cool if it flew! Anyone know?

    Of course it flies!!!!

    isn't 15 feet a bit too short? and do we have to follow strict dimensions to make sure stability while on flight?

    For the monoplane, you can cut out any design as long as it the the point at which you fold the wing down ends a the fuselage, and the wing width is never too short to provide stability. Properly adjusted, I've gotten these planes to fly across a 30' room.

    how big are the cards exactly?

    Hi SoCal..very well done..some people our there just want a Mercedes for the price of a Schwinn LOL..but again Very Nicely Done...not built to break flight records..just for the enjoyment of the build..Thanks again......Tom

    I like the idea and the biplane TOTALLY but I can't follow the steps.

    Thanks for the instructable. I'm a total newbie so forgive me if this sounds silly: would replacing some parts (the parts that don't need to be folded) with foam affect the flight capability of the plane? A reply would be most appreciated.

    Nice Instructable SoDiggerCpl,well thought out and presented,a lot of thought has obviously gone into this project.

    OMG i love building things that can fly! I only use to know how to make paper airplanes n stuff but now with these instructables i can make awsome flying stuff! :D if any1 has any good instructables for other flying crafts that u can make out of household items (that really fly) send em to me pls!:D thx

    is it alright if i post a diffrent version of this?

    Ehh.. Sorry for bad grammar and ignore the first half of my post. Didn't notice the comments were arrannged most recent to mrst ancient,

    AS stated fore by its creator, it glides. One good addition to it would be a rubber band so its propellers could actually propel the plane.

    just made one of these, .. bi plane and wow, looks cool , but it flips around a lot. Any chance of some photos of the finished bi-plane?! (more photos!) I cant quite work out how to weight it properly. Fun though, going to make another one with a shorter fusalage, with all the crashes, it became very damaged.

    If you watch a real plane as it takes off, you'll notice that there are flaps on the wings and tail. While in flight, adjustments of these surfaces control the direction of the plane. If the plane is doing an upwards loop, an adjustment that makes it level off is needed. Adjustments: Plane goes up: Bend points (on the front) of rear wings UP (allows more air to pass under the wing) until flight is stable. Plane goes down: Bend point of rear wings DOWN (lets more air go over the wing) until flight is stable. Plane flies to the left: Bend point of tail LEFT (lets more air past on right) until flight is stable. Plane flies to the right: Bend point of tail RIGHT (lets more air past on the left) until flight is stable. A combination of these steps may be needed. Notice how you bend the points of the control surfaces towards the problem? In a conventional aircraft, the control surfaces are on the rear of the wings, not the front, so an adjustment away from the problem is needed. For my designs though, it looks cooler, and you don't need to cut flaps!
